The nsSOCKSSocketInfo::ConnectToProxy function in Mozilla Firefox before 18.0, Firefox ESR 17.x before 17.0.2, Thunderbird before 17.0.2, Thunderbird ESR 17.x before 17.0.2, and SeaMonkey before 2.15 does not ensure thread safety for SSL sessions, which allows remote attackers to execute arbitrary code via crafted data, as demonstrated by e-mail message data.
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
